usb: usbtest: add a test case to support bos for queue control

In Test 10 of usbtest module, it queues multiple control messages and
thereby tests control message queuing, protocol stalls, short reads, and
fault handling. And this patch add a test case to support queue BOS control
request for USB 3.0 SPEC.
